CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 714,674, dated December2, 1902.

i Application filed August 21,1902. Serial No. 120,475. (No model.)

To all whom, t may concern:

Be it known that I, EDWARD OLIFF, a citizen of the United States, and aresident of Newark, in the county of Essex and State of New Jersey, haveinvented certain new and usefullmprovements in Car-Trucks, of which thefollowing is a specification.

The invention relates to improvements in car-trucks; and it consists inthe novel features and combinations of parts hereinafter described, andparticularly pointed out in the claims.

The object of the invention is to simplify and render more durable andefficient cartruck frames, and the said invention pertains moreparticularly to the side and pedestal frames of the truck.

In carrying out my invention I construct in the preferred embodiment theside frames of the truck from rolled channel-beams cut o at suitablelengths and equipped with pedestal-frames `for the axle-boxes, while thetransoms are also made from rolled channelbeams and havetheir iiangesextended outwardly toward the ends of the truck, the ends of saidtransoms being brought into contact with the inner sides of the sideframes and secured by means of suitable plates. The side frames of thetruck have their flanges extended outwardly, and intermediate the upperends of the axle-boxes and the lower surface of the upper flange of theside frames are provided elliptic springsV bearing against saidaxleboxes. ed in accordance with my invention is one of great durabilityand efficiency and capable of being manufactured without undue expense.

Theinvention will be fully understood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in which- Figure 1 is a side elevation, partly broken away at one end,of a car-truck constructed in accordance with' and embodying theinvention. Fig. 2 is a top view of a portion of same. Fig. 3 is anenlarged side elevation,

" partly broken away, of one end of the side frame of the truck. Fig. 4tis a vertical transverse section through a portion of the truck on thedotted linedl 4. of Fig. 3; and Fig. 5 is an enlarged top view, partlybroken away and partly in section, of a part of one end of Thetruck-frame construct,-A

one of the transom-beams and a portion of a side frame and is presentedto illustrate the method of securing the end of the transombeam to theside frame.

In the drawings I illustrate as much of an electric or passenger cartruck as is suicient to clearly disclose my invention, the oppositesides of the truck-frame being duplicates of each other and one sideframe being fully illustrated.

In the drawings, 10 designates the beam side frames; 11, thetruckwheels; 12, the customary journal-boxes for the car-axles, (notshown;) 13, the elliptic springs bearing upon the upper ends of saidjournal-boxes and confined at their upper portion below the upperoutwardly-projecting iiange 14 of the side frame, and 15 the paralleltransom-beams rigidlyconnecting the side frames of the truck. The sideframes 10 are connected together at their middle portions by means ofthe transom-beams 15 and at each end by a suitable bar 16, the bar 16being of any suitable form or construction and not being specificallyclaimed herein.

The side frames of the truck are each constructed from a rolledchannel-beam having the vertical web portion 17 the aforesaidoutwardly-projecting flange 14. along the upper edge of said webportion, and the corresponding lower flange 18, said lianges 14 and 18both projecting outwardly from the web portion 17 and leaving the innerface of the side frames 10 smooth and regular. frames 10 are each formedfrom a rolled channel-beam cut out at its opposite ends to form thespaces 19 for the journal-boxes 12, said spaces 19 being cut through thelower iiange 18 and through a portion of the web 17, but

not through the upper flange 1li, the flange 14 and a part of the web 17over the spaces 19 being left intact. The journal-boxes12 are partlybelow the lower iiange 18 of the side frames, and the lower portions ofsaid journal-boxes are inclosed on their three sides by thepedestal-frames 20, having the horizontal arms 21, iitting against thelower surface of the flange 18 and rigidly though detachably securedthereto by means of the bolts 22, which extend through said arms 21 andsaid flange 18 and also through the auxiliary pedestal-frame members 23,which are in the nature The side IOO of triangular-shaped castingsfitted upon the upper surface of the lower flange 18 at the oppositeedges of the spaces 19 and affording vertical flanges 24, facing thejournal-boxes 12. The pedestal-frame members 23 in addition topossessing the vertical fianges 24 for the journal-boxes 12 have theflanges 25, fitfing against and riveted to the web 17 of the side frame,and the lower horizontal fianges 26, seated upon the lower iange 18 ofthe side frame and secured thereto by means of the aforesaid bolts 22.The pedestal-frames 20 correspond in width with the width of the loweredges of the side frame, and the guiding-surfaces afforded by them arecontinued upwardly by means of the flanges 24 of the auxiliarypedestal-frame lnembers 23.

,The journal-boxes 12 have upon their upper ends suitable sockets orframes 27 to receive and confine the middle portion of the lower sectionof the elliptic springs 13, the upper sections of which are held insuitable frames 28, riveted fo the lower surface of the upper fiange 14of the side frame, and, as may be observed on reference toFig. 4, thesprings 13 and parts connected therewith, while fully exposed to View,are substantially concealed below the upper flange 14 of the side frame.

Upon the inner ends of the side frames 10- and in line with the ellipticsprings 13 are rigidly secured the frames 30, which define aninverted-U-shaped outline and are of angleiron form in cross-section,these frames 30 being riveted to the inner face of the webs of the sideframes 10 and strengthening that portion of said side frames about thespace 19 for. the axle-boxes and above the linev of the car-axles. i

The side frames 10, as has been explained above, are each made from arolled channelbeam, and the upper and lower fianges of each side frameextend outwardly. At each end of each side frame the channel-beam ispreferably cut out or recessed, as at 3l, to adord adequate space forthe parts to be carried by the truck-frames and for coupling carstogether, the formation of the recesses 31 resulting in an extension 32being formed, and it is to the extensions 32 at ythe ends of the sideframes that the end bars 16 are secured, as shown in Figs. 1 and 2. Thebars 16 are each in one continuous piece, having their ends bentinwardly and extended along the web of the extensions 32 of the sideframes, to which the ends of the said bars 16 are riveted. The webportion 17 of the side frames may be cut out, as at 33, to allow for theprojecting ends of the bolster and its springs (not shown) and, as at34, for permitting the inspection of the interior parts of the truck andthe convenient manipulation or application of said interior parts. Iregard it as important that the side frames are each made from a rolledchannelbeam and that the flanges of the beam extend outwardly, and it isalso an important feature that the spaces 19 are so disposed that aportion of the web and a portion of the lower fiange of the side framesare at opposite sides of each of said spaces, said spaces being setinwardly -from the ends of the side frames. It is obvious that the sideframes made from commercial rolledchannel-beams may be produced at smallexpense, while at the same time said side frames constructed asdescribed possess great durability and are capable of withstanding therough usage to which car-truck frames are ordinarily subjected.

The transoms 15 are of rolled channelbeams corresponding with thechannel-beams from which the side frames 10 are made, and the ends ofthe transom-beams 15 abut against the inner faces of the side frames 10,the ends of said transom-beams beingsecured to the side frames by meanslof the corresponding upper and lower plates 35 36 and angle-iron plates37, the latter being vertically disposed between the upper and lowerflanges of the transom-beams and being riveted to the web portion of thetransom-beams and si de frames, as more clearly illustrated in Figs. 4and.5. The upper and lower plates 35 36 are each in one integral piece,and said plates are riveted to the flanges of the side frames and theanges of the transom-beams. The plates 35, 36, and 37 not only serve toconnect the v ythe said springs being supported by means of suitablesaddles 38, suspended from the transom-beams and affording in theirupper portions suitable rubbing-surfaces for the bolster.

yThe car-truck frame as a whole has been constructed with the view ofattaining great strength, durability, and efficiency at comparativelysmall expense and at the saine time to provide a car-truck frame-inwhich elliptic springs may be employed overthe journal- IOO IIO

boxes in an exposed position, but at the same time substantiallyconcealed below the upper fiange 14 of the side frames. The constructionand arrangement of the pedestal-frame members are also desirablefeatures and constitute a portion of my invention.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In a ear-truck, the channel-beam side frames 10` having their upperand lower flanges 14, 18, extending outwardly from the web portions,said beams at their ends being cut away to form the spaces 19 forl theaxleboxes, and said iianges 14 above said spaces being left intact,combined with the axleboxes, thepedestal-frame members secured to thelower Han ges of said side frames and inclosing the lower ends of saidboxes, the auxiliary pedestal-frame members 23 secured to said sideframes at oppositesides of said spaces, the springs confined at theouter side of said side frames intermediate the upper ends of said boxesand the lower surface ofthe upper flanges 14 of the side frames, andsockets for retaining said springs in position; substantially as setforth.
